Brief introduction of laminating machine

Laminating machine can be divided into two categories: namely coating laminating machine and pre-coating laminating machine. That is, the coating laminating machine includes gluing, drying, hot pressing three parts, its wide range of application, stable and reliable processing performance, is widely used in the domestic laminating equipment. Pre-coating laminating machine, without glue and dry part, small volume, low cost, flexible and convenient operation, not only suitable for the laminating processing of large quantities of printed matter, but also for the laminating processing of small batch and scattered printed matter such as automatic desktop office system, it has a promising future.

Laminating machine is divided into gluing, drying, hot pressing three parts.

1. Gluing part. The gluing part is equipped with adjusting device to adjust the amount of gluing to meet the requirements of different printing pieces. The gluing roller adopts rubber roller or steel roller.

2. Bake road part. The baking path is generally 2 ~ 3m long. The drying passage of the laminating machine is provided with an infrared lamp and an electric fan. There are high power electric heating tubes and exhaust fans in the drying path of automatic laminating machine, the temperature can be adjusted to dry adhesive and exhaust gas.

3. Hot pressing part. This part is the key to laminating, directly related to the bonding fastness of laminating products. The principle of hot pressing is that the adhesive can quickly infiltrate and penetrate into the surface layer of the printing piece in the melting state, so as to obtain a firm binding interface layer. The hot pressing section consists of a set of rollers. One of the hollow metal drum, installed in the electric heat pipe, temperature can be self-controlled. The pressure of this set of rollers can be adjusted.
